eighth); third interstice 2-piinctate on apical half, ninth seriate- 

 punctate; basal border truncate on posterior margin, and joining 

 lateral border at humeral angles without the slightest interrup- 

 tion. Intercoxal declivity of prosternum rounded ; of meso- 

 sternum concave. Length 16-19, breadth 5 -5-6 6 mm.

Differs from N. chalyhaus^ Dej., by head smaller; prothorax 

 much more convex and differently shaped — the widest part at the 

 middle, and the sides equally rounded to apex and base — the 

 apex narrow, with the angles not so wide and nearer the head, 

 the basal angles far less marked, lateral basal impressions shorter 

 and deeper; elytra more convex, with the border of both base 

 and sides less raised, the lateral border being much narrower and 

 not carinate near the base, etc. All my specimens are black, 

 without any metallic tinge.

Elongate, rather convex. Head oval: prothorax hardly broader 

 than long; basal angles subrectangular; posterior marginal punc- 

 ture at basal angle on inner side of border : elytra oval, deeply 

 striate; interstices strongly convex, eighth and ninth narrow; 

 humeral angles dentate; lateral border very narrow, but carinate 

 near base: prosternum with basal declivity flat and bordered; 

 metasternal episterna elongate. Black ; elytra (excepting first 

 interstice and margin) dark purple. 



Head large (3 mm. across eyes), elongate, convex; eyes small, 

 depressed, deeply imbedded in orbits; genjis tumid behind eyes 

 and buccal fissure; each lateral setigerous puncture of clypeus 

 connected by a feeble sulcus ; with a fine puncture at each 

 lateral angle of clypeal suture. Prothorax narrow, very little 

 onger than broad (3-7 x 3*9 mm.), widest (not ampliate) about
